    1. Introduction

    Since the Rio Earth Summit in 1992, many studies have

    concentrated on environmental issues in the tropics, which have

    positively influenced national environmental policies (Glicken,

    2000; Benjaminsen, 2001). However, environmental degradation

    continues to be a major ecological concern in tropical countries,

    where population growth and food production exert increased

    pressure on the ecological system (Nagendra et al., 2004; Wright,

    2005; Etter et al., 2006; Pacheco, 2006). Thus, monitoring land use

    dynamics is essential to tune management strategies that enable a

    balance between production and conservation. For the assessment

    of the land use/cover changes, remote sensing data play a major

    role with their ability to provide quantitative information on the

    spatial dynamics of land cover from different time periods (Tekle

    and Hedlund, 2000; Tottrup and Rasmussen, 2004; Deng et al.,

    2006; Mottet et al., 2006). This technique contributes greatly to a

    global understanding of environmental processes, but analysis at

    the local scale is more complicated. Finer scale studies in the

    Sudano-Sahelian zone reveal the complexity of land use situations,

    which are difficult to predict (Warren, 2002; Wardell et al., 2003;

    Burgos and Maass, 2004).

    Since the 1970s, recurrent drought in Burkina Faso has

    intensified the internal mobility of people towards the southern

    and western parts, which have favorable environmental conditions

    (Boutillier et al., 1985; Henry et al., 2003; Ouedraogo, 2003; Henry

    et al., 2004). Based on satellite images from 1955, 1983 and 1993,

    Howorth and OKeefe (1999) concluded that the population

    increase due to immigration has not led to environmental

    degradation in the southern region of Burkina Faso. However,

    Informed decision on the management of natural resources requires an understanding of the complex

    dynamics of socio-economic and biophysical factors. This study aimed at exploring theland usechange in

    southern Burkina Faso at regional and local levels and the underlying causes of change. The local level

    study was conducted in twovillages, Boala and Yale, in Sissili Province. Aerial photos from 1984 and1997

    and satellite images from 1986 and 2002 were employed to describe the land use dynamics. The spatial

    approach was combined with field data collected in 2003 and 2005 for ground-truth checking and

    gathering other relevant data. Semi-structured questionnaire was used for gathering data on socio-

    economic factors driving land use changes at local level. At regional scale, the annual rate of change in

    forest land, grazingland, galleryforest and cropland was0.4, 0.9, 1.6 and 3.8%, respectively. The size

    of croplands increased by 14% in some districts with an equivalent annual rate of conversion to cropland

    estimated at 0.6% during 19862002. At the local level, the size of croplands increased from 7 to 14% in

    Boala and from 21 to 30% in Yale at the expense of shrinking of forest cover from 78 to 40% in the former

    and from 41 to 18% in the latter village. Rural migration (3.3% at regional level, and as high as 97% in Yale

    and 9% in Boala) coupled with extensive subsistence farming, large-scale commercial farming, intensivefuelwood extraction andother disturbances were the main factorsdriving landuse change.In conclusion,

    the results show that in a decade and half the southern region of Burkina Faso has moved from a sparsely

    populated area with subsistence farming to a more complex zone of production characterized by high

    competition between different land use types. Integrated management of the natural resources in the

    region should, therefore, be given more attention.

    Wardell et al. (2003) found that significant deforestation had in

    fact occurred during the period 19862001 in western and

    southern regions along the Volta River basins. Recently, Braimoh

    (2006) obtained a deforestation rate of 11% in the grassland areas

    and a degradation of 17% in the woodlands of the northern region

    of Ghana for the period 19841999, which has a similar ecological

    zone as the southern Burkina Faso. Based on analysis of satellite

    images from 1986 to 2002, Ouedraogo (2006) found an annual

    deforestation rate of 1% in the Bieha district in Sissili Province of

    southern Burkina Faso. These findings led to the formulation of key

    questions which guided this study: (a) what is the current trend in

    land use in the study area? (b) How can the situation observed at

    the local scale improve understanding of observations at the

    regional (orsub national)scale? (c)Whatare thedrivers of land use

    change? To answer these questions, changes in land use were

    quantified based on multi-temporal spatial data at different scales

    over a 16-year period combined with field-based observation and

    information gathered from farmers. We presented several maps

    that depict the current change in land use, analyzed the impact of

    the change in farming systems on the condition of the forest

    ecosystem and recommended strategies for natural resource

    management.

    2. Materials and methods

    2.1. Study area

    The study was carried out in Sissili and Ziro Provinces, which

    are located ca. 160 km from thecapital (Ouagadougou) in southern

    Burkina Faso (1l8020128000 N and 01830028800W), West Africa

    (Fig. 1). The study area is characterized by low relief with an

    average altitude of 300 m a.s.l. and consists primarily of settle-

    ments, cultivated lands, open savanna woodlands, and small areas

    of deciduous forests. The forest vegetation includescommunity (To

    and Boura) and State protected forests (Sissili classified forest,

    Kabore Tambi national park, Cassou forest exploitation zone).

    According to Fontes and Guinko (1995), the flora of the region is

    dominated by perennial grass species such asAndropogon ascinodis

    C.B.C.I, A. gayanus Kunth, and Schizachyrium sanguineum (Retz.)

    Alston, which constitute the open savanna. The ligneous species

    such as Afzelia africana Smith ex Pers., Khaya senegalensis (Desr.) A.

    Juss. and Pterocarpus erinaceus Poir. are also important fodder

    species. The occurrence of scattered tree species, such as Vitellaria

    paradoxa Gaertn. f., Parkia biglobosa (Jacq.) R. Br. ex G. Don. and

    Tamarindus indica L., on croplands is also a common feature in the

    Fig. 1. Location of the study area.

    study area. This area belongs to the Sudanian or south-Sudanian

    zone according to the phyto-geographical zoning established by

    White (1986) and Guinko (1984), respectively. The mean (S.E.)

    annual rainfall for the years 19952000 was 859.20 31.98 mm and

    the number of rainy days per annum was 53.40 2.54. The average

    annual temperature is 27.1 8C, with a maximum average monthly

    temperature of 31.7 8C in April and a minimum average monthly

    temperature of 25.3 8C in August. The population is constituted of a

    native ethnic group, Nouni, and migrant group mainly Mossi

    (originating from the centre and northwest of Burkina Faso) and

    Fulani (originating from northern Burkina Faso). The average

    population density is 28 inhabitants/km2 in both Sissili and Ziro

    Provinces. The farming system is characterized by traditional

    subsistence farming and cultivation of cash crops (cotton, cashew

    tree) as well as intensive fuelwood extractions and ranching.

    2.2. Land use mapping

    The assessment of changes in theland usewas made at regional

    and local scales. For regional scale study, two satellite images from

    1986 and 2002 were visually interpreted and processed to map

    land cover changes. The basic data source was Landsat satellite

    images (TMand ETM+):Path195 andRow 52 from November1986and October 2002, with 30 m spatial resolution. Administrative,

    topographic and forest maps obtained from the Institute of

    Geography andother sources (Kargougou, 2001; Ouedraogo, 2002;

    Yameogo and Ramde, 2004) were also used during land use cover

    change analysis. The spatial data were further checked for ground-

    truth on 58 plots located by a GPS. Canopy coverand canopyheight

    were used as criteria to define the woody vegetation units as

    follows:

    A forest as woody vegetation with canopy cover >40% and

    canopy height >5 m

    A woodland as vegetation with canopy cover between 15 and

    40%; canopy height >5 m

    A gallery forest as a stripe of woody vegetation occurring alongthe main riverbank.

    To assess the land use dynamics at a local scale, two villages,

    Boala and Yale, from Sissili Province were selected. The two

    villages differ in the level of farming and in the proportion of

    migrant population. To analyze the land use dynamics, aerial

    photographs from 1984 and 1997 and a satellite image from 2002

    were visually interpreted. The photographs were provided by the

    Institute of Geography in Burkina Faso (viz. Mission 84067B Po

    1984, scale 1:50,000; Mission 97158B, Sissili 1997, scale 1:20,000).

    A field survey was conducted in 2004 to collect ground-truth

    information based on 91 plots in Yale and 66 plots in Boala. The

    land use descriptions were based on the nomenclature from the

    Land cover map of Africa (Mayaux et al., 2004). Four land useclasses were identified for visual interpretation: forest land (a

    mosaic of woody vegetation), cropland (land currently under

    cultivation and fallows), grazing land (tree and/or shrub savanna),

    and gallery forest (a stripe of woody vegetation along the main

    riverbank). The mapping was done using GIS tools in Arcview 3.3.

    2.3. Drivers of land use change

    To further understand the land use dynamics, we gathered data

    on factors that could be the underlying causes of land use change,

    such as human population, farming system, disturbances to the

    different land use types and infrastructure development. At

    regional level, data on the population density were drawn from

    the national census reports (INSD, 1989, 1998; MATD, 2005) while

    local census was conducted in the two villages in October 2002 to

    obtain demographic information for the purpose of this study. To

    characterize the farming system, farmers were interviewed about

    their farm conditions such the length of cultivation time, the type

    of crop cultivated, farming techniques, as well as the land tenure

    issues and ownership. To assess disturbances in the forests, a

    systematic stratified sampling design was applied where the

    protected and non-protected forests within a village were

    demarcated first, and then systematically sampled by laying

    circular plots (55 m radius) on grids. Due to a late acquisitionof the

    satellite image from 2002, the sample plots were delineated based

    on a map drawn from the 1997 aerial photograph. In Yale, the plots

    (91) covered 0.9% of the protected area of the village, and the same

    in the remaining non-protected area. In Boala, the plots (66)

    represented 1% of the total area of the village. The assessment

    included number of stumps of trees cut for fuelwood and local

    construction, number of trees pruned for animal feed, number of

    trees uprooted by elephants and the percentage of the plot with

    indicators of grazing (animal trails, hoof print and herbage

    removal). With regard to infrastructure development, we calcu-

    lated the road networks at regional and local scales directly from

    the maps.

    2.4. Data analyses

    After each land use type was delineated, its area and proportion

    of each land use cover to the total area was computed. The change

    in each land use type during the study period was calculated as the

    ratio of the difference in area between years to that of the initial

    year. This change was further divided by the time interval to get

    the annual rate of change. The annual rate of conversion to

    cropland was calculated as the difference in proportion of

    croplands between years divided by the time interval. Data on

    farm attributes were analyzed using descriptive statistics while

    information from interviews and field assessment was summar-

    ized and presented.

    3. Results

    3.1. Land use dynamics at a local scale

    The trend of land use change was similar between the villages,

    although the magnitude of land use change differed. In Boala, the

    proportion of cropland doubled while the grazing land tripled

    during the 16-year period (Table 1A and Fig. 2). Forest land was

    decreased nearly by half in 2002 compared to its coverage in 1984,

    while the size of the gallery forest didnot change much. In Yale, the

    size of crop and grazing lands increased by 9 and 18% in 2002

    compared to thesizes in 1984, while theforest land and the gallery

    forests declined by nearly 50%(Table 1B and Fig. 3). At a local scale,

    the annual rate of conversion to cropland was estimatedas 0.4% for

    Boala and 0.5% in Yale.

    3.2. Land use dynamics at the regional scale

    At the regional level, the various land use types included

    extensive grazing areas, pastoral management unit, subsistence

    and commercial agriculture, conservation forest, and production

    forest mainly for fuelwood extraction (Fig. 4). The actual size and

    proportion of thedifferent land usetypeschangedduring thestudy

    period. In 1986, the grazing land had much higher proportion of

    the total regional area than other land use types while the size of

    croplands was substantially high after 16 years (Table 2). The size

    of other land use types decreased during the study period;

    particularly the decrease was more notable in the gallery forest

    and grazing land. Interestingly, the annual conversion rate to

    croplands varied among districts within provinces. In Ziro

    Province, the lowest conversion rate was observed in Cassou

    and the highest in Bougnounou (Table 3). In Sissili Province, the

    lowest and highest conversion rates were observed in Silly and

    Fig. 2. Land use change in Boala village during 19842002.

    Niabouri districts, respectively, while no conversion was noted in

    Nabielianayou.

    3.3. Drivers of land use change

    There was an increase in population at both regional and local

    levels during the study period. At a regional scale, the annual rate

    of increase in population density was 3.3% with remarkable

    variation among districts within provinces (Table 3). The values

    ranged from 0.7% (Bougnounou) to 5% (Sapouy) in Ziro Province,

    and from 2.8% (To) to 9% (Niabouri) in Sissili Province. The annual

    change in population density showed some correspondence with

    the annual rate of conversion to croplands in most of the districts.

    At a local level, there was also a similar increase in populationwith

    distinct difference in population density between the villages,

    where it was lower in Boala than in Yale (Table 4). It was

    interesting to note the high influx of people into Yale compared to

    Boala, as shown by the high proportion of migrant population in

    the former village.

    The farming system was characterized by large-scale com-

    mercial farming and subsistence farming (mainly in the form of

    shifting cultivation). Large scale farming of commercial crops,

    such as cashew nuts, maize andbeans,was found in seven districts

    within the region with varying land size (Table 5); the highest

    being in Cassou (1228 ha) and the lowest in Bakata (120 ha).

    Attributes of subsistence farms are presented in Table 6. They

    were generally small in size (46 ha/farmer), being put under

    cultivation for longer period by migrant farmers who also put

    higher labor input than the natives while they both had similar

    off-farm activities and farming techniques. With regard to land

    tenure issue, 91% of the migrants got access to land through loan

    while 86% of the natives received land as a gift from parents and

    relatives.

    The extent of disturbance on the different land use types

    differed between villages (Fig. 5). Cutting for fuelwood and local

    construction was common on croplands in Boala while it was

    common on grazing lands in Yale. Pruning of branches and grazinginfluence were largely observed on grazing lands in both villages

    while elephant damage was disproportionately higher on forest

    lands in Boala than Yale. Concerning road networks, we found

    317 km of main and secondary roads, which can be used in all

    seasons in the region, and 45% of the villages lying within 5 km

    radius from the roads. We also found that Yale is situated at a main

    road connecting Burkina Faso with Ghana, while Boala is almost

    isolated and the only road to access Boala is the 34 km secondary

    road and then the 9 km of path unusable during the rainy season

    (i.e., JuneSeptember).

    4. Discussion

    The results from the present study revealed that there was a

    rapid land use change both at local and regional scales. At the local

    scale, the size of crop andgrazing lands increased at the expense of

    shrinking of forest cover with distinct variation in magnitude of

    change between villages. This land use dynamics could be driven

    by the associated increase in population due to migration

    particularly in Yale village, where local migration is dated backed

    to the 1975 (personal communication with villagers). Apparently,

    the proximity of Yale to the road made influx of people higher than

    Boala, which is in line with the important synergetic causeeffect

    relation between population-infrastructure and agricultural

    expansion on tropical deforestation (Geist and Lambin, 2002).

    The increased influx of people to the village is accounted for

    increased in cropland, as migrants are involved not only in

    subsistence farming but also in cultivation of commercial crops

    such as cotton, cashew and beans. Consequently, Yale is nowexperiencing land shortage and most newcomers have to share

    land with established immigrants due to the fact that the protected

    forest reserve covers 50% of the village land coupled with the

    increasing population. The fact that the migrants have user rights

    to the land they obtained by loan illustrates the receptivity by the

    native population (Nuni) and flexibility of the land tenure, which

    has played an important role in the integration of the migrants

    (mainly Mossi and Fulani) in the region, as mentioned by Howorth

    (1999). However, this local land tenure is characterized by some

    restrictions such as precluding tree planting by migrants, which is

    considered as a mark of land appropriation like in many rural areas

    of Burkina Faso. These restrictions are being contested by many

    established immigrants in Yale, who suggest that having lived

    there for over three decades they should have certain privileges aslong as there is no claim on land or a clear intention of

    appropriation. They also suggest that the development of tree

    crops contribute to the improvement of production systems, which

    can be profitable for the village as a whole. This restriction on tree

    planting could have a negative impact on the land use, particularly

    on the diversity of on farm trees. Although the land use right is

    somehow flexible for migrant population, there is a prohibition on

    a woman to own farm land by the traditional land rights.

    The increase in grazing lands in both villages pertains mainly to

    the installation of cattle herders on the protected area of Yale in

    1997 (the Fulani ethnic group). In practice the installation was

    extended to all open access areas of the region. In recent years the

    high density of the cattle herds and uncontrolled grazing practices

    have increased crop insecurity, and the episodic conflicts between

    herders and farmers have become more frequent (Ouedraogo,

    2003).

    Most of the landuse dynamics issues observed at a local scale is

    also reflected at the regional scale. First, there was an increase in

    the size of cropland and population density as well as a change in

    farming system, mainly geared towards cash crop production. This

    increase in population density is associated with a continuous flux

    of immigrants, which in turn alters the traditional agriculture

    production systems (McMillan et al., 1992; Drabo et al., 2003;

    Henry et al., 2003). The important consequence of the population

    increase from influx of people was the high rate of conversion to

    croplands observed in several districts. The regional rate of

    conversion to croplands (0.6%) is twice higher than the national

    rate (0.3%) for the period 19902005 (FAO, 2006). Similarly, the

    annual rate of change in cropland (3.7%) was higher than thenational rate of 1.4% from 1984 to 1997 as reported by Stephenne

    and Lambin (2001). This trend in conversion to croplands was

    confirmed by Ouedraogo (2006) who found a rate of 1% for the

    same period 19862002 in Bieha district of the studied region. One

    important consequence of this conversion is the degradation of

    Sissili protected forest in addition to the increasing illegal activities

    such as charcoal production, hunting, and bush fire occurring each

    year.

    The second important factor is the increasing pressure from

    grazing. A pastoral zone was established in 1998 within the

    protected area to prevent overgrazing problems but the project

    was not successful (Kamuanga et al., 2001). Instead, the high

    density of cattle led to excessive pruning of fodder trees and

    increasing threats to crops due to grazing, thus resulting indeterioration of social relations between herders and farmers. The

    third aspect is the land tenure, which is the same for the region in

    the sense that all the rural lands of the region are under the hands

    of the native ethnic group (Nuni). However, recent studies have

    shown that there is an emerging issue of access to forest resources

    by migrants in the region, particularly in Bougnounou district

    (Zougouri, 2006). At regional scale too, tree planting by migrants is

    not allowed and women has norightto own a land. As inthecaseof

    most areas in Burkina Faso, our study site (the southern region)

    experiences land tenure insecurity, particularly due to increasing

    land transactions for expansion of agri-business (Mathieu, 2001;

    Bologo, 2004). In general, land tenure issue in the country is still a

    subject of contention, as the Land Reform Act of 1984, revised in

    1991 and 1996 (Ouedraogo, 2002) seems not to be fully applied.Several factors contribute to a more complex land usedynamics

    pattern when studied at a regional scale. One is thevarious types of

    resource management systems, which includes traditional sub-

    sistence farming of cereal, intensivefarming of cash cropsand local

    market crops and new systems of fuelwood extraction, ranching,

    agri-business tree planting, protected forest reserve for fauna

    conservation and pastoral management. Another factor is a weak

    dialogue and/or consensus between the multitude of actors (i.e.,

    native subsistence farmers, migrant farmers, migrant cattle

    breeders,private actors) on the access to land and/or itsoccupation

    (personal communication with local stakeholders). Sometimes,

    different types of activities overlap such as the pastoral manage-

    ment of grazing activities located in the Sissili protected forest and

    the extensive area of fuelwood extraction. The subsistence

    croplands are expanding annually and the agri-business occupa-

    tions are gradually increasing into the grazing lands. But at the

    same time, the density of cattle is increasing in theregion, partially

    due to increasing of local herding and mainly due to the

    transhumance of immigrant herders. In this area, there is also

    an increasing interest in community forest management by the

    local populations (e.g., Boura, To, Bori-Nebou and Cassou

    exploitations zones), but Ouedraogo (2001) stressed that the

    reliability of the fuelwood extraction activities in Burkina Faso is

    questionable. In general, the allocation of areas to the different

    activities is not always based on a consensus between the different

    stakeholders (Ouedraogo, 2002; Stakeholders communication in

    2003). This factor is increasing the competition among different

    land use types in the region.

    Thecomplexityof thecurrentland usedynamicsuggests a need

    for integrated management in the region. Successful cases of local

    initiatives in other areas of Burkina Faso exist from which we could

    learn (Hansen and Reenberg, 1998; Reenberg and Lund, 1998;

    Brasselle et al., 2002). Insecurity to access and use of land is often

    caused by exogenous factors that are not adapted to the local

    conditions (Ouedraogo et al., 1996; Reenberg et al., 1998), but on

    the other hand the adaptation of traditional land tenure rights to

    the socio-economic context of land use change is important for theimprovement of the natural resource management systems

    (Ouedraogo et al., 1996; Reenberg and Lund, 1998; Drabo et al.,

    2003; Mwangi and Dohrn, 2007). To this end some important

    conditions are needed, which include local rights recognition,

    equity in benefits for actors, and consensus on collective choices

    (Hermosilla, 2000; Sulser et al., 2000; Ribot, 2001). Resources

    management strategies should be built from experience and

    lessons, and also need to be based on factual land use ( Castro and

    Nielsen, 2001; Sandewall et al., 2001) where understanding of the

    various local situations is valuable (Reenberg, 2001).

    5. Conclusions

    This study on land use dynamics in southern part of BurkinaFaso shows that in a decade and half the southern region has

    moved from a sparsely populated area with subsistence farming to

    a more complex zone of production characterized by high

    competition between different land use types. The land use

    change, both at local and regional levels, is moving toward

    increased cropland at the expense of destructing the forest

    vegetation, mainly due to population increase from immigration,

    the dominance of extensive farming systems, and emergence of

    commercial large scale farming. The increasing pressure on forests

    from uncontrolled grazing, bush fires, highconversion to croplands

    as well as fuelwood extraction are all contributing factors to the

    decline in forest cover. Integrated management of the natural

    resources in the region should, therefore, be given more attention.

    To this end, the following recommendations are forwarded: (a)facilitate local dialogue among the various stakeholders to reach a

    consensus on land use; (b) regulate the influx of people to the

    region, grazing intensity to reduce the increasing pressure on the

    forest resources; (c) empowering local communities in manage-

    ment and conservation of forest resources; (d) follow-up of the

    land use changes in the region, and the methods used in this study

    can be seen as a potential tool for such monitoring.
